Body Mass Index (BMI)

Find your healthy weight using the BMI calculator

Body Mass Index (BMI) assesses your body weight relative to your height. The American Dietetic Association uses the following BMI formula: multiply your weight in pounds by 700. Then divide
that number by your height in inches two times.

For example: a person weighs 135 pounds and stands 5’7” tall. 135 pounds x 700 = 94,500. Divide that twice by 67” (5’7”). 94,500/67 = 1,410 divided by 67 again = BMI is 21

BMI was designed to determine how your weight affects the status of your health. Too high of a BMI means that you are more prone to illnesses such as heart disease, cancer and diabetes. A pear-shaped person, who has excess weight in their hips and thighs, is at a much-decreased risk of many diseases than is an apple-shaped person, who has much of his or her weight in the chest and abdominal area.
